description Rigorously critique concept designs through intellectual scrutiny. This skill should be used when validating concept definitions, reviewing concept quality, identifying design flaws, or evaluating whether something qualifies as a true concept.

Concept Critic

Overview

Apply rigorous intellectual scrutiny to concept designs, challenging assumptions, identifying gaps in reasoning, and validating against the 8 essential criteria. This skill demands precision and doesn't accept vague or poorly-reasoned concepts.

When to Use This Skill

Use concept-critic when:

  • Reviewing a concept definition for quality and completeness
  • Validating whether something qualifies as a concept vs feature/class/service
  • Identifying design flaws before implementation
  • Challenging assumptions in concept design
  • Evaluating operational principles for specificity and value

Critique Philosophy

Challenge the concept's reasoning through rigorous intellectual scrutiny:

  • Question assumptions and identify gaps in logic
  • Demand evidence for claims about user value
  • Point out logical fallacies and weak reasoning
  • Don't accept vague generalizations or unsupported claims
  • Focus on genuine critical thinking, not encouragement

Key questions to always ask:

  • What evidence supports this purpose statement?
  • What counterarguments haven't been considered?
  • Is the operational principle truly compelling and specific?
  • Are there hidden dependencies on other concepts?
  • Does this actually provide end-to-end value?

Critique Workflow

Step 1: Verify Essential Structure

Check that the concept includes all required elements:

  • Purpose statement (one clear sentence)
  • Operational principle ("if...then" format)
  • State definition (data structures)
  • Actions list (operations)

If any element is missing: Stop and demand the complete definition before proceeding.

Step 2: Validate Against the 8 Criteria

Rigorously check each criterion from references/concept-criteria.md:

1. User-Facing

  • Question: Do users directly experience this functionality?
  • Red flag: If it's purely technical/internal, it's not a concept
  • Challenge: Describe a specific user interaction. If you can't, this fails.

2. Semantic

  • Question: Does this represent meaningful behavior beyond UI/implementation?
  • Red flag: If it's just about how things look or are coded, it's not semantic
  • Challenge: Explain the meaning without mentioning technical details. Can't do it? Not semantic.

3. Independent

  • Question: Can this be explained without referring to other concepts?
  • Red flag: If you need to mention other concepts to explain it, it's coupled
  • Challenge: Define it completely standalone. Dependencies indicate poor design.

4. Behavioral

  • Question: What specific behaviors does this enable?
  • Red flag: If it's just static data with no actions, it's not a concept
  • Challenge: Demonstrate the behavior in the operational principle. No behavior = not a concept.

5. Purposive

  • Question: What single, valuable purpose does this serve?
  • Red flag: Multiple purposes, vague benefits, or no real user value
  • Challenge: State the purpose in one sentence. Need two sentences? You have two concepts.

6. End-to-End

  • Question: Can users achieve the full purpose with this concept alone?
  • Red flag: Incomplete functionality that provides no standalone value
  • Challenge: Write the operational principle. If it trails off ("then... ???"), it's incomplete.

7. Familiar

  • Question: Have users seen similar functionality elsewhere?
  • Red flag: Completely novel concepts that users won't understand
  • Challenge: Name 2-3 apps with similar concepts. Can't name them? Users will struggle too.

8. Reusable

  • Question: Could this work in other applications or contexts?
  • Red flag: Tightly bound to one specific app's implementation
  • Challenge: Describe it in a different domain. Can't generalize? It's too specific.

Step 3: Critique the Operational Principle

The operational principle reveals whether the concept delivers real value. Apply harsh scrutiny:

Check for specificity:

  • ❌ "If you use X, then good things happen" - Too vague
  • ❌ "The system does X automatically" - No user action
  • ❌ "If you do X, then Y occurs" - Y must be valuable, not just state change
  • ✅ "If you upvote quality content, then the best items rise to the top" - Specific action, specific value

Demand compelling value:

  • What problem does this solve that's worth the complexity?
  • Why would users care about the "then" part?
  • Is this actually valuable or just restating what the system does?

Test with edge cases:

  • Does the principle hold for all uses of the concept?
  • Are there scenarios where the "if...then" breaks down?
  • What happens with empty states or boundary conditions?

See references/operational-principles.md for detailed validation patterns.

Step 4: Check for Anti-Patterns

Identify common design flaws:

Multi-Purpose Concepts

  • Symptom: Concept tries to solve multiple unrelated problems
  • Example: Facebook's Reaction (approval for algorithm + emotional signal to author)
  • Fix: Split into separate concepts with single purposes

Incomplete Functionality

  • Symptom: Can't write a compelling operational principle
  • Example: Registration without authentication checking
  • Fix: Add missing actions to complete the end-to-end functionality

Hidden Dependencies

  • Symptom: Concept can't be explained without referring to others
  • Example: Comment that only works with specific Post structures
  • Fix: Make polymorphic with generic types

Non-User-Facing

  • Symptom: Concept is purely technical/internal
  • Example: Database connection pooling, caching strategies
  • Fix: This isn't a concept - it's an implementation detail

Implementation Leakage

  • Symptom: Definition includes technical details about how it's built
  • Example: "Uses a Redis cache to store session tokens"
  • Fix: Focus on user-facing behavior, not implementation

Step 5: Provide Direct Critique

Don't sugarcoat findings. If the concept is flawed, say so clearly:

For good concepts:

  • Acknowledge what works well
  • Identify potential improvements
  • Suggest how to strengthen the operational principle

For bad concepts:

  • State explicitly why it fails criteria
  • Identify the fundamental flaw (multi-purpose, incomplete, coupled, etc.)
  • Recommend specific fixes or whether to abandon/redesign

For questionable concepts:

  • Articulate the specific concerns
  • Ask pointed questions that expose gaps
  • Demand clarification on vague or unsupported claims

Red Flags Checklist

When reviewing a concept, watch for these warning signs:

  • Vague purpose: Can't state the problem in one clear sentence
  • Weak operational principle: No specific user action or valuable result
  • Multiple purposes: Features seem unrelated to stated purpose
  • Incomplete actions: Can't achieve purpose with available operations
  • Hidden dependencies: Need to mention other concepts to explain it
  • Technical focus: Defined by implementation rather than user behavior
  • No familiar examples: Can't name similar concepts in other apps
  • Not reusable: Too tightly bound to specific application context

Quality Standards

Hold concepts to these standards:

Purpose Statement

  • Must: One sentence, clear problem statement
  • Should: Reference user needs, not technical requirements
  • Should not: Mention implementation details or other concepts

Operational Principle

  • Must: "If [user action], then [valuable result]" format
  • Must: Specific action and specific value delivery
  • Should: Be compelling enough to justify the concept's existence
  • Should not: Be vague about action or value

State & Actions

  • Must: Minimum required for purpose fulfillment
  • Should: Use generic types for reusability
  • Should not: Include implementation details or excessive complexity

Independence

  • Must: Explainable without referencing other concepts
  • Should: Work standalone in multiple contexts
  • Should not: Have dependencies on specific implementations
